Provenance (Imperial Radch)

Though she knows her brother holds her mother's favor, Ingray is determined to at least be considered as heir to the family name. She hatches an audacious plan--free a thief from a prison planet from which no one has ever returned, and use them to help steal back a priceless artifact.

But Ingray and her charge return to her home to find their planet in political turmoil, at the heart of an escalating interstellar conflict. Together, they must make a new plan to salvage Ingray's future and her world, before they are lost to her for good.
